Gelation in Alginate-Based Magnetic Suspensions Favored by Poor Interaction among Sodium Alginate and Embedded Particles. WebA vast majority of alginate particles exist as spheres in most practical uses, and both the particle shape and size are the key factors dominating the applications and performance of alginate gels. Therefore, it becomes an issue of great interest to investigate the aspheric alginate particles. As the first step, various shaped alginate particles were formed due …
WebAlginate is a natural polysaccharide that has been recently gaining increasing attention as a biomaterial in the field of tissue engineering due to its favourable biocompatibility and gelation properties. Alginate hydrogels are commonly made by ionic crosslinking in the presence of divalent cations. WebMar 27, 2014 · Alginate can be cross linked by external gelation methods allowing the alginate-drug solution to be extruded as microsphere droplets into a CaCl 2 solution [ 10 ]. Gelling of alginate occurs when the divalent cations participate in the interchain bonding between G-blocks, giving rise to a three-dimensional network in the form of a gel.
